The Helmy Aerogypt was a British four-seat cabin monoplane designed and built by Egyptian Saleh Helmy at Heston Aerodrome in 1938. The Aerogypt I was a low-wing cantilever monoplane initially powered by three 22 hp (16 kW) Douglas Sprite engines. The aircraft had an upward hinged roof that acted as a landing flap. Registered G-AFFG, it first flew in 1939. It later had the hinged roof removed, and was re-designated the Aerogypt II. Another modification added end plates to the horizontal tail surfaces, and was re-designated the Aerogypt III, and last flown in that configuration in September 1940.Jackson (1974)
In 1943, the aircraft was modified as the Aerogypt IV with a tricycle landing gear and two 65 hp (48 kW) Continental A65 engines. It was flown from White Waltham Airfield, but in November 1946 it was damaged beyond repair when it was dropped by the recovery crane following a landing accident at RAF Northolt.Smith (2002)
